f0fcb2d59f Symmetric changes to md4.go as for md5.go. 
Use uint index variables in some cases instead
of int to enable strength reduction; this makes
it possible for the compiler to reduce % into
masks.

Old code: 6g -S md4.go md4block.go | grep "md4block.go:44"
0471 (md4block.go:44) MOVL    AX,BX
0472 (md4block.go:44) MOVL    AX,BP

0478 (md4block.go:44) IMULL   $4,BP
0479 (md4block.go:44) SUBL    BP,BX
0480 (md4block.go:44) MOVLQSX BX,BX

0485 (md4block.go:44) MOVQ    (BP),BP
0486 (md4block.go:44) MOVL    (BP)(BX*4),DI

New code: 6g -S md4.go md4block.go | grep "md4block.go:44"

(I was looking at this code accidentally because of some gofmt

c1045db1d8 go_spec: use PrimaryExpr as type switch expression 
Without this change, the spec parses <-c.(type) as (<-c).(type)
but parses <-c.(int) as <-(c.(int)).

With this change, the former parses as <-(c.(type)).

All three parsers already implement this rule, because
they look for the "type" word during parsing of a standard
type assertion.  This change merely brings the
spec in line with the implementations.

e1033d07b4 Add query to find number of subexpressions. 
This was convenient for me to have without being forced
to parse the regexp myself. I'd understand if it's not
really wanted, but I also think that some meta information
about compiled regexps would be fine.

50d6c81d4a runtime: fix race condition 
(Thanks to ken and rsc for pointing this out)

rsc:
	ken pointed out that there's a race in the new
	one-lock-per-channel code.  the issue is that
	if one goroutine has gone to sleep doing

	select {
	case <-c1:
	case <-c2:
	}

	and then two more goroutines try to send
	on c1 and c2 simultaneously, the way that
	the code makes sure only one wins is the
	selgen field manipulation in dequeue:

	       // if sgp is stale, ignore it
	       if(sgp->selgen != sgp->g->selgen) {
		       //prints("INVALID PSEUDOG POINTER\n");
		       freesg(c, sgp);
		       goto loop;
	       }

	       // invalidate any others
	       sgp->g->selgen++;

	but because the global lock is gone both
	goroutines will be fiddling with sgp->g->selgen
	at the same time.

This results in a 7% slowdown in the single threaded case for a
ping-pong microbenchmark.

Since the cas predominantly succeeds, adding a simple check first
didn't make any difference.
